Great location! The best you can find close to Asok station and Terminal 21.
Gerd was a great host, and made everything to make our check-in and stay as easy and smooth, while taking care for all things immediately, gave us some tips about the area and was always available in place.
The apartment is large, where you really feel like home, building located in a dead end short street, which is very quiet and half a minute walk from Sukumvit, Asok station, Terminal 21 and Robinson, and across the street you have huge Top's supermarket open 24/7.
You have TV with plenty of channels in many languages, kitchen with all the necessary stuff, and a quite and clean pool to to help you start a Bangkok day. The building entrance is guarded.
Highly recommended! This is location winner and price/benefit ratio rare to find in this area.
